Can we use Brightness,shape, size, orientation in our definitions of constancies

[Boots]

Could you elaborate young Visionz?

[Glockmeister]

Because the discovery that C is incorrect was made by Australians?

[Boots]

Wah?

[Glockmeister]

Wah?

Confused?

Two Australian Doctors, Drs Robin Warren and Barry Marshall were awarded the Nobel Prize for Medicine or Physiology for, "for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease".

Personally i think it is ridiculous if we can't. It would be different if we were defining brightness. but we are defining the psychological term 'brightness constancy,' it is stupid to use a synonym which means the same thing.

Could you tell me what they conlcuded?

Well, basically, they found that there was a bacterium in the intestine, H. pylori, which was causing these peptic ulcers, not hot foods or stress.

yeah mate .. whilst you are correct and they did find out that its the bacterium not stress

dont ever forget .. stress does NOT cause disease .... it can be a contributing factor . but does not cause the disease ...

when we are stressed .. our bodies resistance to disease is increased ( since we release cortisol and our body is attempting to fight the stressor , the bodies focus on maintaining homeostasis is altered) ... B lymphocytes and T lymphocytes ( white blood cells) are produced to a lower extent.

what im trying to say is ... stress reduces our immunity to pathogens ( diseases) such as bacteria .. and hence .. this allows the bacterium to get past our defenses ( immune system) easier

note : . dont forget .. stress DOSN'T cause disease , its only a contributing factor

[Boots]

Yeah thanks, but still how does knowing that help me answer this question. Because although D is correct, it says 'more likely'

VCAA 05'
Studies of people who are suffering long-term stress indicate that they
A. show some ill-effects early on but recover quickly.
B. recover gradually from any ill-effects but do not have lasting effects of the stress.
C. are more likely to have ulcers than problems with high blood pressure.
D. are more likely to show poor health later in life.

[matt123]

ummmm ....yeah i can see how it might be D ... the question proves info that states " LONG TERM STRESS" ..
long term generally means its been going on for a while haha
so then the immune system is weakened for a while .. and they are more susceptible to disease ....

the thing is .. like you said . its 2005 exam ... that's the first year of this new course  , things were still being tested and learned ...
the examiners didnt know as much as they do know about this topic
so generally any questions this year will be short and direct and just allow us to apply knowledge

anyways g2g do chem paper goodluck

essentially C and D are the same thing, but C seems too specific, stress is a subjective experience and we all cope differently with it. someone may go their whole life with high levels of stress and never have a stomach ulcer or heart attack. D seems to be an umbrella answer, and it seems more logical as the question doesn't state anything about heart conditions or...whatever causes stomach ulcers, just what the effects of long term stress are.

YES THATS THE ANSWER I WAS LOOKING FOR, STRESS IS SUBJECTIVE

well H.pylori is pretty resistant to immune attack even in people who are healthy and not stressed, it can live for ever in a person if they don't get treatment

but in general yeah... high levels of whats it called cortisol? suppresses the immune system
